According to such an animal litter box, even when the supporting container having the tray after the animal has excreted is pulled out, the rear side wall portion of the supporting container can be reduced from contacting the bottom portion of the upper container, and the possibility of the excrement leaking to the outside of the tray can be reduced.
In this animal litter box, it is preferable that the upper container bottom part is separated from the 2 nd wall part in a state where the top end of the bottom surface of the pull-out part is in contact with the placement surface and the top end of the 1 st wall part of the support container is in contact with the upper container wall part in a state where the animal litter box is placed on the placement surface.
According to such an animal litter box, even in a state where the front end of the bottom surface of the drawer portion abuts on the placement surface and the upper end of the 1 st wall portion of the support container abuts on the upper container wall portion, since the upper container bottom portion does not contact the 2 nd wall portion, it is possible to reduce the possibility that the excrement leaks to the outside of the tray due to the contact of the support container and the upper container bottom portion.
In the animal litter box, it is preferable that the upper end of the 2 nd wall portion is higher than the upper end of the tray.
According to such an animal litter box, the possibility of rearward leakage of excrement can be reduced by the 2 nd wall portion that is higher than the tray for receiving excrement.
In the animal litter box, it is preferable that the upper end of the 2 nd wall portion is lower than the upper end of the tray.
According to such an animal litter box, since the upper end portion of the tray is not covered with the 2 nd wall portion, a user or the like who cares for the animal can easily grasp the rear end portion of the tray.
As the animal litter box, it is desirable that the tray includes: a planar receiving portion provided at a central portion in the front-rear direction and the left-right direction, the planar receiving portion receiving the excrement; and a tray front-side wall portion, a tray left-side wall portion, a tray right-side wall portion, and a tray rear-side wall portion that define the receiving portion, the tray rear-side wall portion including 3 rd wall portions and 4 th wall portions, the 3 rd wall portions and the 4 th wall portions being provided on both outer sides of a portion overlapping the upper container bottom portion in the left-right direction, respectively, an upper end of the 4 th wall portion being lower than an upper end of the 3 rd wall portion.
According to such an animal litter box, even when the supporting container having the tray after the animal has excreted is pulled out, the rear side wall portion of the tray can be reduced from contacting the bottom portion of the upper container, and the excrement can be prevented from leaking to the outside of the tray.
In the animal litter box, it is preferable that the upper container wall portion has an upper container contact point overlapping with an end of the upper end of the 1 st wall portion on the inner side in the left-right direction, and a distance in the up-down direction between a lower end of the upper container wall portion and the upper container contact point is equal to or less than the predetermined distance.
According to such an animal litter box, the upper container wall portion and the 1 st wall portion abut against each other at a position closer to the upper container bottom portion in the left-right direction than in a case where the distance in the up-down direction between the lower end of the upper container wall portion and the upper container contact point is larger than the predetermined distance, and therefore the possibility of the 2 nd wall portion coming into contact with the upper container bottom portion can be reduced.
In the animal litter box, it is preferable that the front wall portion has 5 th wall portions provided on both side portions in the left-right direction and a 6 th wall portion provided between the 5 th wall portions, an upper end of the 6 th wall portion is located lower than an upper end of the 5 th wall portion, a length of the 2 nd wall portion in the left-right direction is longer than a length of the 6 th wall portion in the left-right direction, and an upper end of the 2 nd wall portion is located higher than an upper end of the 6 th wall portion.
According to such an animal litter box, by having the 2 nd wall portion longer in the left-right direction, the possibility of the rear wall portion coming into contact with the bottom portion of the upper container is further reduced, and by making the upper end of the 5 th wall portion lower, the possibility that the work of the user for lifting the tray is hindered by the front wall portion can be reduced.

Fig. 1 is a schematic perspective view of an animal litter box 1 according to the embodiment. Fig. 2 is an exploded explanatory view of the animal litter box 1. Fig. 3 is a diagram illustrating the structure of the animal litter box 1. In the following description, three directions orthogonal to each other are referred to as a front-rear direction, a left-right direction, and an up-down direction. The center line C-C in fig. 4A and the like indicates the center of the animal litter box 1 in the right-left direction, and the animal litter box 1 has a shape that is symmetrical to the center line C-C in the right-left direction.
As shown in fig. 1, 2, and 3, the animal litter box 1 includes an upper container 10, a main body 20, a tray 30, a support container 40, a lid 50, and an output main body 60. The upper container 10 is disposed from above the main body 20, and the lid 50 is disposed above the main body 20 and the upper container 10. The tray 30 is disposed inside the support container 40, and the support container 40 in a state in which the tray 30 is stored (supported) is stored so as to be able to be pulled out to the front of the main body portion 20. The main body 20 is placed on the output main body 60 from above.
When used as an animal litter box, a plurality of granular excrement treatment agents (not shown) are placed on the bottom surface of the inside of the upper container 10, and an absorbent sheet (not shown) is disposed in the receiving portion 31 of the tray 30. The excrement disposal material is a so-called cat litter, which is a granular disposal material that absorbs or permeates excrement such as urine of animals. The excrement disposal material has water repellency and allows a large amount of liquid to pass through the liquid absorbent member. If an excrement treating agent which easily absorbs liquid is used, the excrement treating agent absorbs much urine, and it is difficult to accurately measure the urine amount. However, even a water-repellent excrement treatment agent sometimes absorbs a certain amount of urine. In the case of using such excrement, the amount of urine may be corrected according to the type of excrement treatment material used when detecting the amount of urine. The absorbent sheet is a sheet member capable of absorbing liquid such as excrement (urine), and a rectangular sheet member obtained by laminating and joining a liquid-permeable front sheet, a liquid-retaining intermediate sheet, and a liquid-impermeable back sheet can be used. Hereinafter, the animal litter box 1 in a state of use in which the animal litter box 1 is mainly used will be described, and the excrement treating agent and the absorbent sheet are omitted in the drawings and the like.

As shown in fig. 1, 2, and 11, the lid 50 is disposed above the upper container 10 and the main body 20, and has a lid opening 51 on the upper side. The cover 50 covers the front side portion of the upper opening of the upper container 10. The lid 50 reduces the possibility that the excrement treating agent stirred up by the animal leaks to the outside of the animal litter box 1. The animal litter box 1 covers the front portion of the upper container 10, thereby reducing the possibility of the excrement treatment agent leaking out of the animal litter box 1 when the animal has excreted toward the rear side and then has stirred up the excrement treatment agent with the rear legs.
< structure of output main body portion 60 >)
As shown in fig. 2, the output main body portion 60 includes an upper output portion 61 and a lower output portion 62 located below the upper output portion 61. The upper output portion 61 and the lower output portion 62 each have a rectangular shape in plan view and have a predetermined thickness. The upper output unit 61 is mounted on the lower output unit 62. The upper output unit 61 has a tray contact portion 61a on the upper surface, with which the tray 30 is brought into contact, and at least 1 or more upper load cells (not shown) as output units are provided inside the upper output unit 61. The tray contact portion 61a is a flat surface extending over the entire area of the upper output portion 61. The lower output unit 62 includes a lower load cell 63 as an output unit and a control unit (not shown). The lower load cells 63 are provided at four corners of the bottom surface of the lower output unit 62, protrude downward, and support the entire leg of the animal litter box 1. The upper load cell and the lower load cell 63 are each a compression type sensor of a cylindrical shape that converts applied force into an electric signal and outputs the electric signal.
The control unit is connected to the upper load cell and the lower load cell 63 by wired or wireless signal lines, and receives signals output from the respective load cells. The control unit includes a communication unit (not shown), a storage unit (not shown), and a processing unit (not shown). The communication unit is a part that performs wireless communication with terminals such as a force sensor, a smart phone, and a tablet terminal. The storage unit is constituted by a RAM, a ROM, and the like, and is a portion for storing various data and programs. For example, the detected weight before excretion, the weight of excrement, the number of excretion times, a correction value associated with the excrement treatment agent, and the like can be stored. The processing unit is constituted by a CPU or the like, and is a part for performing various calculations. For example, calculation processing is performed to calculate the weight of excrement from each detection result such as the weight before excretion and the weight after excretion stored in the storage unit.
Action of measuring weight of excrement in animal litter box 1
Fig. 12 is a schematic view of a cross section shown in a-a direction in fig. 11. In fig. 12, the upper container 10 and the lid 50 are omitted. As described above, in the tray 30 in a state where the container 40 is pulled out from the main body 20 and supported, the supported portion 32 of the tray 30 is supported by the supporting portion 41 that supports the container 40. On the other hand, in the tray 30 in the use state, the bottom surface of the tray 30 is in contact with the upper discharging portion 61, is supported by the upper discharging portion 61, and is placed on the upper discharging portion 61 without being in contact with the supporting portion 41 for supporting the container 40. The main body 20 including the upper container 10 and the lid 50, and the upper output unit 61 supporting the container 40 and mounting the tray 30 are mounted on the lower output unit 62. Accordingly, the gravity of the tray 30 acts on the upper discharging portion 61, and the gravity of the upper container 10, the main body portion 20, the supporting container 40, and the lid 50 does not act thereon. That is, in the case of receiving excrement by the tray 30, the upper load cell does not detect the weight of the upper receptacle 10, the main body 20, the support receptacle 40, the lid 50, and the animal in the upper output portion 61, but detects the weight of the tray 30 and excrement. The absorbent sheet is loaded as the weight of the tray 30, and the excrement treatment agent is loaded as the weight of the upper container 10.
Specifically, a method for measuring the weight of excrement is described. The storage unit stores in advance the weight detected as the force received by the upper load cell in a state where the animal is not placed in the animal toilet and the weight detected as the force received by the lower load cell 63. That is, the result of detecting the weight of the tray 30 and the absorbent sheet by the upper load cell is stored in the storage unit as the initial tray weight, and the result of detecting the weight of the upper container 10, the main body 20, the support container 40, the lid 50, and the excrement treatment agent by the lower load cell is stored in the storage unit as the initial body weight.
When an animal such as a cat enters the upper container 10 from the front side of the animal litter box 1, the force applied to the lower load cell 63 increases as the weight of the upper container 10 (body portion 20) increases. At this time, the lower load cell 63 outputs a signal corresponding to the received force. The control unit that receives the signal stores the detection result received as the signal in the storage unit as the pre-excretion weight, and the processing unit calculates the difference between the pre-excretion weight and the initial body weight stored in the storage unit to obtain the weight (body weight) of the animal.
When the animal urinates on the upper container bottom 11, the urine passes through the gap between the excrement treating agents and the through hole h, and falls downward toward the receiving portion 31 of the tray 30. As a result, the weight of the tray 30 receiving urine increases, the force received by the upper load cell from the tray 30 increases, and the upper load cell outputs a signal corresponding to the force received by the tray 30. The control unit stores the detection result received as the signal as the weight of the tray after excretion. The processing unit calculates the difference between the initial tray weight and the post-excretion tray weight stored in the storage unit to obtain the weight of the animal's excrement (urine).
The control unit can transmit the obtained weight of the excrement to the terminal of the user through the communication unit and display the weight on the screen of the terminal. The control unit may transmit and display various data obtained without being limited to the weight of the excrement. The obtained data are the number of excretions, the time at which the excretion was performed, the body weight of the animal, and the like. The collection of the data may be shown in a graph or a table.
< about 1 st wall part 42df and 2 nd wall part 42ds >
Fig. 13 is a diagram illustrating a positional relationship between the upper container 10 'and the supporting container 40' of the animal litter box as a comparative example. As shown in fig. 13, in the animal litter box shown as a comparative example, the upper container bottom 11 ' of the upper container 10 ' is closest to the rear side wall 42d ' in the center portion in the left-right direction. Therefore, when the supporting container 40 'is drawn out from the used animal litter box 1', there is a possibility that the lower surface of the upper container bottom 11 'comes into contact with the upper portion of the rear side wall portion 42 d'. In particular, in the animal litter box having the output body portion capable of measuring the weight of the animal excrement, since the distance between the lower surface of the support container 40 ' and the ground surface is long, when the support container 40 ' is pulled out to the front side, the support container 40 ' is easily inclined so that the front side contacts the ground surface and the rear side faces upward. As a result, when the upper container bottom 11 'comes into contact with the upper portion of the rear side wall portion 42d and the rear side wall portion 42 d' moves forward after use so as to scrape off excrement (urine) attached to the lower surface of the upper container bottom 11 ', there is a possibility that the excrement may leak to the outside of the supporting container 40'.
In this regard, in the animal litter box 1, the rear wall portion 42d includes the 1 st wall portion 42df and the 2 nd wall portion 42ds, and thus the possibility of the excrement leaking to the outside of the tray 30 and the outside of the supporting container 40 is reduced.
Fig. 14 is a diagram illustrating a positional relationship between the upper container 10 and the supporting container 40 of the animal litter box 1. As shown in fig. 14, on both outer sides of the portion of the rear side wall portion 42d that overlaps the upper container bottom 11 in the left-right direction, first wall portions 42df, 42df are provided. Further, a 2 nd wall portion 42ds is provided between the 1 st wall portion 42df on the left side and the 1 st wall portion 42df on the right side. The upper ends of the 1 st wall portions 42df on both sides have the same height and are bilaterally symmetrical about the center line C-C. The 2 nd wall portion 42ds is symmetrical with respect to the center line C-C, and the height of the upper end of the 2 nd wall portion 42ds is lower than the height of the upper end of the 1 st wall portion 42 df. Further, a distance Lw between the upper end position of the 1 st wall portion 42df and the upper end position of the 2 nd wall portion 42ds is longer than a distance Lb which is a predetermined distance by which the upper container bottom 11 protrudes downward (Lw > Lb).
Since the upper container bottom 11 has a distance Lb protruding downward, it is highly likely to contact the rear side wall 42 d. Therefore, by providing the 2 nd wall portion 42ds in the portion overlapping the upper container bottom portion 11 in the left-right direction, the possibility of the upper container bottom portion 11 coming into contact with the rear side wall portion 42d can be reduced. If the contact between the upper container bottom 11 and the rear side wall 42d is prevented, even when the supporting container 40 is pulled out forward from the main body 20 after the animal has excreted, for example, when the absorbent sheet disposed on the tray 30 is replaced, the possibility that the excrement adheres to the supported portion 32 of the tray 30 or the excrement leaks to the outside of the supporting container 40 can be reduced, and the excrement adhering to the output main body 60 or the mounting surface G does not need to be disposed of.
Further, from the use state in which the animal litter box is placed on the placement surface G, as shown in fig. 15 and 16, the support container 40 is pulled out from the main body portion 20, and in a state in which the front end of the bottom surface of the pull-out portion 43 is in contact with the placement surface G and the upper end of the 1 st wall portion 42df of the support container 40 is in contact with the upper container curved portion 12, it is preferable that the upper container bottom portion 11 is separated from the 2 nd wall portion 42 ds. Fig. 15 is a diagram for explaining a state in which the pull-out portion 43 is brought into contact with the mounting surface and the upper end of the 1 st wall portion 42df is brought into contact with the upper container curved portion 12. Fig. 16 is a schematic view of a cross section taken along line K-K in fig. 15. The state in which the front end of the bottom surface of the pull-out portion 43 is in contact with the placement surface G and the upper end of the 1 st wall portion 42df of the support container 40 is in contact with the upper container curved portion 12 is also the state in which the support container 40 is tilted to the maximum extent in the vertical direction. Even in such a state, since the upper container bottom 11 is separated from the 2 nd wall portion 42ds, the supporting container 40 can be reduced in the possibility of contacting the lower surface of the upper container bottom 11, scraping the excrement, and leaking to the outside of the supporting container 40.
As shown in fig. 12, the upper end of the 2 nd wall portion 42ds is preferably located higher than the upper end of the tray 30. Since the 2 nd wall portion 42ds is provided at the upper end of the tray 30, that is, at a position higher than the supported portion 32, the 2 nd wall portion 42ds can function as a wall portion that reduces the possibility of leakage of excrement received by the tray 30 to a position rearward of the rear wall portion 42.
The upper container curved portion 12 has upper container contact points P on both sides in the left-right direction, which overlap with the left-right direction inner ends of the upper ends of the 1 st wall portions 42df in the left-right direction, respectively. Preferably, a distance Lp between the lower end of the upper container curved portion 12 and the upper container contact point P is equal to or less than a predetermined distance Lb of a portion protruding downward of the upper container bottom portion 11 (Lp ≦ Lb). As shown in fig. 16, the upper receptacle contact point P is a point of contact in the case where the upper receptacle 10 is closest to the supporting receptacle 40. The upper container 10 and the support container 40, which are in contact with the upper container contact point P, cannot be further approached in the up-down direction. As shown in fig. 12 and the like, the upper container curved portion 12 is curved upward, and the rear side wall portion 42 has a 1 st wall portion 42df, and the 1 st wall portion 42df has a higher upper end on both sides in the left-right direction. Therefore, the upper container contact point P is located further outward in the left-right direction, and the upper container bottom 11 and the 2 nd wall portion 42ds are in a state of being easily brought into contact with each other. In this regard, if the distance Lp between the lower end of the upper container curved portion 12 and the upper container contact point P is equal to or less than the distance Lb, the upper container curved portion 12 can be brought into contact with the 1 st wall portion 42df at a position closer to the upper container bottom portion 11 in the left-right direction than when the distance Lp is larger than the distance Lb, and therefore the possibility that the 2 nd wall portion 42ds will come into contact with the upper container bottom portion 11 can be reduced.
As shown in fig. 10A and 10B, the front side wall portion 42a also preferably has a 5 th wall portion 42af and a 6 th wall portion 42as having an upper end lower than the 5 th wall portion 42af, as in the rear side wall portion 42 d. The length of the 1 st wall portion 42df in the left-right direction is Mdf, and the length of the 2 nd wall portion 42ds in the left-right direction is Mds. The length of the 5 th wall portion 42af in the left-right direction is Maf, and the length of the 6 th wall portion 42as in the left-right direction is Mas. The height of the upper end of the 1 st wall portion 42df is equal to the height of the upper end of the 5 th wall portion 42 af.
In such a configuration, the length Mds in the left-right direction of the 2 nd wall portion 42ds of the rear side wall portion 42d is preferably shorter than the length Mas in the left-right direction of the 6 th wall portion 42as of the front side wall portion 42a (Mds < Mas). More preferably, the upper end of the 2 nd wall portion 42ds is higher than the upper end of the 6 th wall portion 42 as. That is, the length Mdf in the left-right direction of the first wall portion 42df on one side in the left-right direction is shorter than the length Maf in the left-right direction of the second wall portion 42af on one side in the left-right direction (Mdf < Maf), and the distance Lw between the position of the upper end of the first wall portion 42df and the position of the upper end of the second wall portion 42ds is shorter than the distance Lv between the position of the upper end of the second wall portion 42af and the position of the upper end of the second wall portion 42as (Lw < Lv).
By providing the second side wall portion 42ds having a longer length in the left-right direction in the rear side wall portion 42d of the support container 40, the possibility that the upper container bottom 11 will come into contact with the support container 40 when the support container 40 is pulled out from the main body portion 20 can be easily reduced. On the other hand, when the support container 40 is pulled out, the front side wall portion 42a that first projects outward of the main body portion 20 is less likely to contact the upper container bottom portion 11 with the support container 40. The 6 th wall portion 42as of the front side wall portion 42a is a portion where the user easily grips the tray 30 from the supporting container 40. Therefore, the 6 th wall portion 42as does not need to be increased in length in the left-right direction as the 5 th wall portion 42 as. Further, by making the distance Lv longer, the hand is easily inserted between the 6 th wall portion 42as and the tray 30, so that the user can easily take out the tray 30.
Other embodiments are also possible
The above embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the present invention. It is needless to say that the present invention can be modified and improved without departing from the gist thereof, and the present invention includes equivalents thereof.
In the above embodiment, the position of the upper end of the 2 nd wall portion 42ds is set higher than the position of the upper end of the tray 30, but the present invention is not limited thereto. The upper end of the 2 nd wall portion 42ds may be positioned at the same height as the upper end of the tray 30 or may be positioned lower than the upper end of the tray 30. Fig. 17 is a schematic cross-sectional view of the animal litter box 100 according to another embodiment, the cross-sectional view being viewed from the rear of the center in the front-rear direction. As shown in fig. 17, since the upper end of the 2 nd wall portion 42ds is lower than the upper end of the tray 30, when the tray 30 is gripped during cleaning or the like, a hand is likely to be inserted between the 2 nd wall portion 42ds and the upper end of the tray 30, and the tray 30 is likely to be gripped.
In addition to the 1 st wall portion 42df and the 2 nd wall portion ds provided in the support container 40, the tray 300 may have a structure having a 3 rd wall portion 320f and a 4 th wall portion 320 s. Fig. 18 is a diagram illustrating a tray 300 according to another embodiment. Specifically, the tray 300 includes a tray front wall portion 320a, a tray left side wall portion 320b, a tray right side wall portion 320c, and a tray rear wall portion 320d defining the receiving portion 31, and the tray rear wall portion 320d includes a 3 rd wall portion 320f and a 4 th wall portion 320 s. The upper end of the 4 th wall part 320s is located lower than the upper end of the 3 rd wall part 320 f. Further, the 3 rd wall portions 320f are provided on both sides of the portion overlapping with the upper container bottom 11 in the left-right direction, and the 4 th wall portions 320s are provided between the 3 rd wall portions 320 f.
By using the tray 300, as shown in fig. 3 and 15, when the support container 40 is pulled out from the main body portion 20, even when the tray 30 is inclined more largely in the vertical direction than the support container 40, the possibility that the tray rear-side wall portion 320d of the tray 300 comes into contact with the upper container bottom portion 11 can be reduced.
In the above embodiment, the weight of the obtained excrement is displayed on the terminal of the user through the communication unit, but the present invention is not limited thereto. For example, the animal litter box 1 may be provided with a display unit (not shown), and the weight of excrement may be displayed on the display unit by performing wireless or wired communication between the control unit and the display unit.
In the above embodiment, the animal litter box 1 is configured to be able to be drawn out and inserted while the tray 30 is supported by the support container 40, but the present invention is not limited thereto. For example, the tray 30 may be configured to be able to be directly inserted into and extracted from the main body 20 while supporting the container 40 integrally with the main body 20.
In the above embodiment, the output main body 60 including the upper output unit 61 and the lower output unit 62 is provided, but the present invention is not limited thereto. For example, the output main body 60 may be configured to include only the upper output unit 61 and place the main body 20 or the like directly on the ground surface G, or the lower output unit 62 may be configured to be a simple base without a load cell and be an output unit for measuring only the excrement without measuring the weight of the animal.
